My invention relates to an improvement in containers, and more particularly the type of containers readily adaptable for containing butter, lard, or any dry or semi-liquid substance for shipping purposes.

It is the purpose of my invention to provide a waterproof and greaseproof container which is so constructed to withstand a great amount of strain without damage. My construction is particularly adaptable to use on laminated tubs of paper or other material, and it is my object to make the laminations greater in number at points where the container is subjected to greatest strain.

'11; is the purpose of my invention to provide a means of reinforcing the cover of the container, :so that it. will hold its proper shape and resist transverse strain as would occur when a container was being squeezed-transversely between two objects. .By this means I have been able to provide a laminated paper tub' which will withstand'more strain by several times than a wooden container of similar size and of greater Weight.

I It is an object of my invention to provide a means for holding the cover of the container in place, and of sealing the cover against tampering with the contents of the container. By, this means, I am able to further reinforce the container top against various types of strain to which; the container might be subjected. My cover-holding means despite these advantages and important features, is readily openable when desired, and may be closed quickly and easily.

It is a feature of the preferred form of my construction that the cover-securing means acts to reinforce the top or cover of the container against downward strain imposed by an article or another container placed on the top cover of the container. This is accomplished by providing a pair of crossed metal bands which secure the cover in position, and which transmit compression strain across the top and to the edge of the .cover where the strain may be borne by the side walls of the container.

j .-It is a feature of my invention that the coversecuring means may be entirely removed from the bodyof the tub when it is desired in order that the tub may be reconditioned. The removability of the securing means also permits this means to be readily replaced, as the securing means is more easily worn out than is the body of the tub, and may'need replacement before the container is worn out.

These and other objects of my invention will be more fully and clearly set forth in the following specification:

Figure 8 is a perspective view of a detail portion of the container reinforcing band used in the modification illustrated in Figure 6.

Figure 9 is a perspective view of a detail portion of my securing means.

Figure 10 discloses the band of Figure 8, used in conjunction with cover straps as shown inFigures 1, 2 and 3.

As best illustrated in Figure 2 of the drawings, my container A is formed with side walls l0 formed of a number of laminations of paper II or other suitable material. The side walls preferably taper, as illustrated, for nesting purposes. Between each lamination of paper is a coating l2 of waterproof or greaseproof glue, providing a plurality of waterproof surfaces through which no moisture or greasecan penetrate.

A bottom of laminated paper I3, is likewise provided with a waterproof and greaseproof glue portion thereof are slightly thicker, due to a greater overlap of the laminations, which are formed of a number of separate sheets secured together. In this manner, the lower .portionof 155 the container is capable of withstanding a great amount of strain.

The cover IQ of the container A is formed in a manner similar to the bottom |3 of a series of sheets 20 held together by means of water proof and greaseproof glue, and is substantially flat with a downturned flanged edge 22 about the perimeter thereof. This flanged edge 22 is reinforced by means of a metal hoop 23 of the type indicated in Figure 4. The hoop 23 is bent slight- 1y inwardly at its upper edge 24, and is bent or crimped over the flanged edge as shown in Figures 2 and 3 to entirely enclose this edge.

In preferred form, the cover I9 is held in place upon the container by a harness B illustrated in Figures 1, 2 and 3. The harness B comprises a hoop 25 of just sufficient diameter to slip up over the tub from the bottom thereof to a position spaced somewhat from the top edge 26 of the container side wall Hi. This hoop 25 is provided with two pairs of oppositely disposed offset portions 21 whichaccommodate straps 28 and 29 to encircle the hoop at these points while it is in position on the container.

One end of each strap 28 and 29 encircles the hoop 25 in one of the offset portions, and is held by the clip 30 securely to the hoop at all times. The clip 38 merely encircles the looped ends of the strips, and is crimped in such a manner to hold the strip in this position. The extreme end 32 of each of the strips 28 and 29 is bent down over the clip 30, as shown in Figure 2.

The other end 33 of each of the strips 28 and. 29 is secured to the hoop 25 at a point diametrically opposite the permanently fixed end by looping this end 33 under the hoop 25 at the diametrically opposite offset portion 21, looping this end .33 around the hoop 25, and inserting this end through a slidable clip 34 on the strip 28 or 29. The clip 34 merely encircles the strip 28 or 29 and the end 33. When the end 33 has been inserted through the clip 34, this clip may be slid down adjacent the hoop 25. For additional security, the end 33 of the strip 28 or 29 may be bent down over the clip 24 to prevent this clip from sliding upwardly, although there is little danger of this. The formation of the clip 34 may be seen in Figure 9 of the drawings.

In order to enable the shipper to secure the cover tightly in place, a hole 35 is formed in the end 33 of each of the strips 28 and 28. A tool such as a common nail may be inserted through this hole to enable the shipper to better grasp the strip for drawing it tight.

The hole 35 may also serve the purpose of permitting a seal 36 to be looped through the offset 21 of the hoop 25 and through the hole 35 when the clip 34 is engaging the end 33 of the strip 28 or 29. The top or cover |9 then cannot be removed until this seal is broken or the wire securing the seal is out. In this manner the cover may be sealed against tampering, and the shipment would not be received if a seal was broken.

For shipping purposes, the hoop 25 and the straps 28 and 29 are enclosed within the cover IS in the manner illustrated in Figure 5 of the drawings. The covers, containing the harness B, can be packaged separately from the side wall and bottom portions of the container, which are nested together in shipping.

. If it is desired, I may make the cover IS in the manner illustrated in Figure 6, in which the cover is further reinforced by means of an inner hoop 31 to whichare secured attaching strips 38 at intervals' about the periphery thereof. This inner hoop 31 is placed within the flanged edge 22 of the cover I9, and is held in position by the hoop 23, which is crimped up over the inner hoop 31 as well as over the edge 22.

A flat band 4| encircles the container A in the approximate position occupied in the preferred structure by the hoop 25, and is provided with offset portions 39 forming lips through which the ends of the attaching strips 38 may pass. The free ends 40 to these attaching strips 38 are then bent upwardly and inserted under the flanged edge 22 of the cover l9 as illustrated in Figure 6 of the drawings. The formation of the oiIset 'portions 39 may be seen in Figure 8.

It is obvious that, if desired, the two forms illustrated may be combined, and the fiat band 4| may be used in combination with the crossed strips 28 and 29. Similarly, the hoop 25 could be used with the modification of cover illustrated in Figure 6, being used in place of the flat band 4|.

In shipping, the modification of cover illustrated in Figure 6 would appear as illustrated in Figure 7 of the drawings. The flat attaching strips 38 are bent down parallel with the flat portion of the cover I9, and the covers are bundled one against the other.

If found desirable for certain purposes the hoop 25 or the flat band 4| could be attached to'the side walls of the container. In Figure 8 I illustrate the band 4| being indented at points 42 about the periphery of the same, forcing these indentations into the side walls In and thus preventing relative movement of the band and the side wall Ill. The entire container including the side Walls I8, bottom I 3 and cover I9 is dipped into a paraiiln solution or other surfacing material which coats the outside surface of the material and also is absorbed into the paper and into any cracks between various laminations or adjoining parts. This coating effectively preserves the surface of the containers. In reconditioning the containers, it is possible to steam the same to remove the surface paraffin, and recoat the tubs.

In accordance with the patent statutes, I have described the principles of my invention, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that this is only illustrative of a means of carrying out my invention, and that obvious changes may be made Within the scope of the following I claims without departing from the spirit of my invention.
